I live very close to the second largest particle accelerator (except it was still the largest when I was there) the Tevatron and never worried about anything going haywire. I think there is more probability of a nuclear power plant exploding.

Same here.

Interestingly, if you look at history, the same doomsday theories were around when the Tevatron and other accelerators have went online. Some people simply suffer from mass paranoia, while others look at the facts.
